IMPROVED EGG-BEATER.

Specification forming part of Letters Patent No. 40,11 dated October (i,1863.

To all whom, t may concern,.-

Be it known that l, PETER SCHILDECKER, of the city of Pittsburg, in thecounty of Allegheny and Sta-te ot' Pennsylvania, have invented a new anduseful Improvement in Egg- Beaters; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the annexed drawings, forming part of this specification,in which- Figure 1 is a front view of my improved egg-beater, the capwhich forms the front end being removed. Fig. 2 is rear end view ot' myimproved egg-beater. Fig. 3 is a vertical section ot' myegg-beaterthrough the axis of the cylinder. Fig. 4 is a perspective representationof the cap or movable end piece.

In the several figures like letters refer to similar parts.

My improved egg-beater is designed to beat up the white of eggs or eggsmixed with sugar, and by the use of it I am enabled to accomplish theresult more etfectually and in a much shorter space of time than by handor by the use of any contrivances for a similar purpose with which I amacquainted.

My apparatus consists of a horizontal cylin der, a, which may be made oftin or other suitable material, which is supported 011 a lightframe-work, b. It is closed at the rear end, o, but the front end isfurnished with a movable cap or cover, d, the rim e of which laps overthe end of the cylinder a, as seen in Fig. 3.

ln the rim e of the cap are two shaped slots, j', which arediametrically opposite to each other, and which pass over two pins, g g,on opposite sides of the cylinder a, close to its frontend, so that byplacing the cap on the end of the cylinder, with the pins g g enteringthe slots j' in the cap, and then turning the cap a short distanceround, the cap is se curely fastened on the end ofthe cylinder, thusclosing it up so as to prevent the escape of any of the contents of thecylinder.

At the forward end and lower part of the cylinder a is al spout, h,sloping downward, through which the contents of the cylinder pass whenthe cover is removed.

In the center of the cylinder a is a horizontal shaft, i, which issupported at the rear end by entering the round hole bored in the shaftk, and at the front end by entering a hollow projection, l, in thecenter of the movable cap d. This shaft t' is prevented from turning onits axis, when the machine is in use, by a pin, m, attached to theoutside of the cap d, which may be pressed down so that its lowerextremity enters a hole, 0, in the projection l on the cap, and passesthrough a corresponding hole in that part ofthe shaftt which is seatedin the projection l, as seen in Fig. 3.

To the horizontal shafti are rigidly attached a number of arms, n n',which are set in pairs at uniform distances along the shaft, two arms, nfn, at each point being set at right angles to each other, as shown inFig. l.

The beater consists of aframe composed of a number of parallel bars, p,placed at uniform distances apart, so that each bar p will come betweena pair of arms, n af, when in place in the cylinder a. These bars p areconnected together by two horizontal slats, q q', one of which, q,connects one extremity of all the bars p, and the other, q', connectsthe other extremity of all the bars p.

In the center of each bar r is a ring, through which the horizontalshaft t' passes, the bars turning on the shaft t' as their center. Thebar lo', at the rear end of the beater-frame, has a square box-flangearound the ring at its center, in which box flange the square end of theshaft lo enters, as seen in Fig. 3, at the rear end of the machine, sothat by the revolution of the shaft la the beater-frame is caused torevolve around the stationary arm-shaft t'.

The rapid revolution of the crank-shaft k is effected by means of apinion, s, fastened on the outer extremity of the shaft k, and whichgears into a larger cog-wheel, t, which revolves with its shaft u inbearings in the framework b of the machine by means of the crank c.

On top of the cylinder a is a funnel, w, the V aperture at the bottom ofwhich corresponds with a circular opening, w, in the cylinder. Thefunnel w is fastened to a slide, y, which slides back and forth on topof the cylinder, so that when the funnel is pushed in one direction itsaperture corresponds with the opening in the cylinder, and when pushedback again the opening in the cylinder is closed.

Vhen it is designed to use my machine, the funnel is slid so as to openthe cylinder at the top, the cap or cover d being iirst fastened overits front end. The eggs or eggs and sugar, or whatever is intended to bebeaten, are inserted through thefunnel w, which is then closed, and therapid-revolution of the beaterframe is commenced and kept up until theeggs are beaten up into a lrm froth, which will measure twice as much asthe eggs or eggs and sugar did when placed in the beater. This processtakes only a small portion ofthe time which would be required to producethe same result were the operation performed by hand With an ordinarybeater, and much more eft'ectually. The operation, when performed byhand, is extremely tiring, and requires to be kept up withoutintermission, because if suspended for even a very brief space ottimethe eggs begin to sink back into their fluid state more rapidly thanthey can be beaten up into froth. Then the eggs 'are completely beaten,the cap d is taken oit',

when the froth will run out through the trough, or may readily beremoved.

It is an important feature of my machine `that the axis of the cylinderis horizontal with a beater revolving round the axis ot` the cylinder7because thereby a larger proportion of the contents ot' the cylinder isbrought by the beaters into contact with the air than if any of thebeaters revolved in the luid Without passing in and out of it at eachrevolution. Vhat I claim as my invention, and desire to secure byLetters Patent, ,is-

1. An egg-beater consisting-of the combination of a horizontal closedcylinder, having stationary arms u a', around and between' PETER'SGHILDECKER.
